JFrame not presenting any Components

Question

I am using the following code to create a very simple JFrame, but for some reason it doesn\'t show any components, just a blank frame. Why is this happening? I

Answer 1

Better your first add components to your variable "panel" and add then your finished panel to the .getContentPane().add().

And the most important issue is that you better call frame.setVisible(true); at the end of your method.

Answer 2

Put frame.setVisible(true); after adding components to JFrame, and it will show all the added components. Moreover, you should use specific layout rather than setting bounds for components. You can use a Layout Manager.

Answer 3

You have to move frame.setVisible(true); to the end of the method; the visibility must be set to true after you have added the components.

Alternatively, you can add the following to the end of your method:

frame.revalidate();
frame.repaint();

to revalidate and repaint the frame with the newly added components although I recommend the former method.

Answer 4

you can add this at the end;

frame.pack()
